How mobile phones work!






your mobile phone is constantly trying to find the closest and best signal.
it does this by sending out radio waves and waiting for a receiving signal, the first radio wave to be received back is in theory the clearest and  best signal.

Mobile phone receivers are placed in different location as to try and give u the best signal even when you are on the move!

When you make a call using you mobile phone, a signal goes from you phone to a receiving cell, it then get verified, (this means if you have no credit on your phone, or if you contract has been terminated you will be stopped at this point) assuming your phone has been verified your signal will get transmitted to a 'mtso' (mobile telephone switching office) which will change the direction of your call to the person you are trying to call. this is required for example if the person you are calling is part of a different telephone network to you. the signal then goes to the nearest cell to the person you are trying to call, and then goes form there to there phone.
